The narrow confirmation of Betsy DeVos as Secretary of Education has served as a catalyst for renewedconflict over public education in the United States. DeVos is a strong proponent of private education and charter schools, and this concerns supporters of a strong public school system. Social science comparing the two approaches shows distinct benefits of public schools and questions whether more choice in schooling really helps everyone.

The argument for private and charter schooling is based on the benefits of competition: when public schools don’t perform well, offering parents a broader set of choices forces them to compete and improve. While people often worry about public schools “failing,” it turns out that many schools with low standardized test scores actually do fine in terms of learning outcomes and whether learning persists over the summer.

School choice can also reinforce inequality because people in poor and minority communities rarely have a similar set of schools to choose from. Many social scientists have found that the positive outcomes for students in charter schools are often limited to more privileged or affluent children.

Regardless of the possible benefits of competition that supporters of private schools claim, public schools simply do better when they receive more funding — funding that could be at risk if funds and focus are shifted primarily to private schools.
